Women in the U.S. still experience a major gender wage gap, 55 years after the Equal Pay Act was passed, Business Insider reports. On average, American women earn 80 cents for every dollar their male counterparts earn, according to a report by the Senate Joint Economic Committee Democratic Staff. Their annual earnings are roughly $10,500 less than men. Women also make less than men regardless the educational difference between the two, per the report. “A woman with a graduate degree earns $5,000 less than a man with a bachelor’s degree,” the report says.

The report, “Real Action is Needed to Give American Workers the Raise They Deserve,” highlights that the real hourly wage for the median worker has only grown less than 0.2 percentage point per year on average since 1979. The Republican tax law does little to solve this problem, with 99.2 percent of the benefits going to the top 5 percent of households once it is fully implemented. Instead of leading to broadly shared wage gains, the tax bill is likely to exacerbate the trends we are already seeing.

The political battle over the effects of the Republican tax cuts is heating up, with Democratic lawmakers on the Joint Economic Committee releasing a set of interactive maps Monday designed to show voters just how well wealthier taxpayers are doing under the tax overhaul.

Joint Economic Committee Democrats today announced the launch of their first interactive map which will allow users to understand critical data and policy issues through visual formats on JEC’s website. This first interactive data set details how many years of a typical American family’s bills could be supported by the $193,000 one member of the top 0.1 percent will receive from the Republican tax law. It shows how many years it could support their household income, health care premiums, child care costs, and electric bills by state.
